Definitions

  • the invention relates to an inclination adjustment device with a freely pivoting device for the back part of a motor vehicle seat.
  • This type of inclination adjustment device is known from DE 102 32 030 A1.
  • a device part affixed to the seat part and a device part affixed to the back part are each fixedly connected to adapters, which partially fit around the other device part and consequently make possible an axial locking.
  • a swash mechanism is provided for adjusting the inclination of the back part, said swash mechanism pivoting two parts of the inclination adjustment device steplessly against each other.
  • the folding movement of the back part is accordingly made possible by the further coaxial functional level of the adapter affixed to the back part; to achieve this, the axially added adapter affixed to the back part is axially secured to the inclination adjustment device.
  • Axial retention means such as arcurate bearing points, for example, leave sufficient space for the pivot movements; that is, the inclination adjustment and the folding movement after loosening of the latching means. In virtue of this free space, however, there is the risk that in the event of overload due to the transverse forces generated in the gearing of the swash mechanism, the device parts are spread apart and the device part consequently opens.
  • DE 197 15 764 C2 discloses a device for adjusting inclination having a freely pivoting device, wherein an axial retaining device of the device parts affixed to the back part and to the seat frame is obtained by a covering hood and a stud.
  • DE 43 24 734 C2 discloses a device for adjusting the inclination of a back part of seats having a hinge part affixed to the seat.
  • the object of the invention is to provide a inclination adjusting device having a freely pivoting device for the back part of a motor vehicle seat, which makes possible on the one hand an adjustment of the inclination within the comfort range of the back part and a folding of the back part in the freely pivoting position and on the other hand permitting an axial locking of the device in the event of transverse forces occurring in the device.
  • This object is achieved by a device for adjusting inclination and a method for assembling or manufacturing said type of device for adjusting inclination.
  • an additional axial bayonet retaining device which forms a positive gripping around between the upper part of the device for adjusting inclination and the pivot bearing affixed to the back part.
  • This bayonet locking device is seated advantageously centrally and in the enclosed zone and can therefore provide a considerable resistance against an opening of the device.
  • the bayonet retaining device is formed preferably by an axially projecting bayonet ring with radially protruding bayonet springs provided on the upper part and bayonet grooves provided in the pivot bearing.
  • bayonet springs and bayonet grooves reach into a superimposing rotary position only during assembly not, however, after joining the components, wherein the adapter is connected with the bottom part and the pivot bearing with the bearing part, because the corresponding rotary position lies outside of the pivot ranges of the folding movement and the inclination adjusting movement.
  • the bayonet retaining device can further serve in positioning in the assembly operation, in that it holds the pivot bearing at the time of bolting with the bearing part—which, for example, may be configured as a bearing plate.
  • FIG. 1 represents a illustration of a device for adjusting inclination exploded axially viewed from the center of the back part outwards;
  • FIG. 2 represents a corresponding illustration with assembled parts and with the pivot bearing rotated counter-clockwise;
  • FIG. 3 a radial section through III-III of FIG. 2 .
  • a device for adjusting inclination 1 has an inclination adjuster 2 with a bottom part 3 and an upper part 4 that can be pivoted opposite to the lower part 3 within the comfort range and locked in its pivot positions, a pivot bearing 5 provided concentric to the inclination adjuster 2 on the back part pivot axis A for attachment to a back part support, an adapter 6 for axial clamping of the pivot baring 5 on the inclination adjuster 2 and for fastening to the seat frame of the motor vehicle seat and a bearing plate 7 for axial clamping of the upper part 4 of the inclination adjuster 2 on the pivot bearing 5 .
  • two weld connections 8 , 9 are formed in the weld zones 10 , 11 of the bottom part 3 and weld zones 12 , 13 of the adapter 6 , whereby these to are coupled together rigidly in the rotational sense.
  • the adapter 6 is fastened to the seat frame of the motor vehicle seat using screw holes 14 in two screw connections provided for this purpose and clamps the pivot bearing 5 with its axially protruding arcuate clamping zone 16 with clearance at the upper part 4 of the inclination adjuster 2 .
  • a slider (not shown) made of plastic is inserted into an opening 17 of the clamping zone 16 .
  • the bearing plate 7 is torsionally rigidly fastened to the pivot bearing 5 using bolts 18 and has a clamping zone 20 for axial clamping of the upper pan 4 to the pivot bearing 5 .
  • a slider (not shown) made of plastic is fastened in an opening 21 of the clamping zone 20 .
  • the adapter 6 and the bearing plate 7 consequently serve in the axial locking of the inclination adjuster 2 and the pivot bearing 5 , so that these are not spread apart axially in the event of transverse forces.
  • the axial bearing 5 is welded in the weld zones 22 to the back pan support.
  • the upper part 4 has on its upper side a gearing 24 for receiving a gear pawl (not shown) fastened to the pivot bearing 5 and adjustable by means of a control 26 .
  • the control 26 is guided in an arcuate slot 27 of the pivot bearing 5 , advantageously spring biased in its lower position for engagement of the gear pawl in the gearing 24 and can be adjusted upwardly for releasing using a flexible control cable, for example.
  • the gear pawl is latched into the gearing 24 , such that the pivot bearing 5 is connected torsionally rigidly with the upper pan 4 .
  • the inclination adjustment zone of the inclination adjuster 2 is—as can be seen in FIG. 2 , defined by the stops 30 , 31 of the upper part 4 and the adapter 6 fastened to the lower pan 3 .
  • the pivot bearing 5 can be freely folded forward with the bolted bearing plate 7 and the welded seat back support.
  • the back pan folding range for adjusting the back part of the seat in a partially folded-forward easy-entry-position is defined by the stops 32 , 33 between the adapter 6 and the pivot bearing 5 .
  • a posterior stop for the seat back folding range is formed by the bolts of the left bolts 18 of FIG. 1 , 2 and a stop 34 .
  • the inclination adjuster 2 and the pivot bearing 5 are locked complementarily by a bayonet retention device or bayonet locking device against an axial spreading apart.
  • the bayonet retention device has an axially projecting bayonet ring 36 with two bayonet springs 37 protruding radially outwardly and to bayonet grooves 38 , complementary to the bayonet springs 37 , formed on the pivot bearing 5 , provided on the upper part 4 .
  • the bayonet ring 36 can be fastened to the other metal sheet pressed part of the upper part 4 by a resistance weld 39 , for example.
  • a well-known swash mechanism shown in the section of FIG. 3 —can be configured between the upper part 4 and the lower part 3 , wherein an eccentric means 40 performs a tumbling movement and the upper part gearing of the upper part 4 rolls on the gearing 42 of the lower part 3 .
  • a slight toothing difference 40 to 39 , for example—is formed in known fashion for creating a higher gear reduction.
  • other inclination adjusting gearing can also be used for this purpose.
  • the bayonet ring 36 is passed together with the bayonet spring 37 through the bayonet grooves 38 in the joint—rotary position shown in FIG. 1 and then the upper part 4 and the pivot bearing 5 are rotated counter to each other; in FIG. 2 the pivot bearing 5 is turned counterclockwise vis-à-vis the upper part. Then the weld connections 8 and 9 are formed between the lower part 3 and the adapter 6 and the boltings between the pivot bearing 5 and the bearing plate 7 by means of the bolt 18 .
  • An external cover plate 45 with a plastic clip 46 extending axially through the inclination adjuster 2 is used for assembly, said plate axially holding together the inclination adjuster 2 during handling and assembly, in that it presses against the lower part 3 with the edge of the disk and with its plastic clip 46 opposes the eccentric means 40 .
  • the swivel bearing 5 is initially not secured by the cover plate 45 ; because the bayonet spring 37 grips behind the swivel bearing 5 , the pivot bearing 5 is also axially locked, so that a secure bolt process is secured for connecting the swivel bearing 5 with the bearing plate 7 .
